And? She's the leader of the women's rights movement and a part of her belief was ANTI BLACK and not inclusive. That's why womanism was created which represents the feminist movement FOR BLACK WOMEN. You obviously have no idea what you're talking about. It's called intersectionality.
The problem with your argument is that you assume that feminism is just a western thing. It wasn't. Also, Susan B. Anthony was not the leader of the Women's Rights movement. I'm not sure where you got that. Susan B. Anthony was a leader in women's suffrage, which isn't women's rights in full, but a part of it. Susan B. Anthony was a leader within feminism, but to say she was THE leader, of an international movement for women to gain equal rights is fictitious and goes against recorded history. Feminism historically did not have a chosen leader, and pretending that it did and is not true to history. At that point, you might as well call MLK the leader of the black rights movement; he wasn't. He was just one guy in a big movement with his own opinions and ways to get there.
It's like saying believing in black power means you support black supremacy and superiority. You can have one without the other.
More than that, you're splitting hairs in regards to the womanist thing. In practical terms, womanists are feminists. You're just calling it another name. It's not a wholly different ideology.
